Replacement circulation pump.
I’m here looking for a expierenced/ professional opinion regarding the replacement of a circulation pump.
Recently my home hydronic circulation pump Grundfos up26-99bf has started to sound extremely loud and as if there are quite a few marbles rolling around inside of it.
I’ve contacted a local supplier and they can’t seem to find a direct replacement.
My home is small, a 958 sq/ft slab on grade bungalow. 3 heating zone loops, 1/2 pex is whats in the slab. Water is heated via Bradford white combi unit.
It seems there are a ton of replacement pumps and I’m curious if it is possible for me to replace my pump with a different one if the supplier cannot find a direct replacement. Thanks in advance, let me know if there is any additional information that may be required to spec a proper pump.
